Abstract

During surgical procedures, suction is often used to clear the field to allow better visibility of the tissue. It is possible that the instrumentation or tubing that provides the suction can become clogged with tissue and reduce or completely stop suction. To clear the clogs takes time and often takes the attention away from the surgical task. The following concepts are provided to reduce the frequency of clogging events, and improve methods of resolving them.

SYSTEM TO MITIGATE, SENSE, AND FLUSH CLOGS IN SURGICAL DEVICES 

SUMMARY 

During surgical procedures, suction is often used to clear the field to allow better visibility of the tissue.  It is possible that the instrumentation or tubing that provides the suction can become clogged with  tissue and reduce or completely stop suction. To clear the clogs takes time and often takes the attention  away from the surgical task. The following concepts are provided to reduce the frequency of clogging  events, and improve methods of resolving them.  

DESCRIPTION 

A system is defined with a medical device capable of suction, a second device that provides a suction  source, and a third device that provides a pressure source. It is assumed that irrigation is provided. Refer  to illustration below. 

The first element of the system is to include a lubricant in the irrigation fluid. As the suction device  removes irrigation fluid from the surgical field, it will become lubricated and therefore less likely to clog. 

The second element is to monitor suction pressure and/or suction flow rate to automatically detect a  clog. When suction pressure rises above a given threshold, and/or suction flow rate drops below a given  threshold, the system could provide an alert to the user and prompt them to clear the clog.  Alternatively, the system could act independent of the user to remove the clog. 

The third element includes multiple means of clearing the suction path. In all cases, pressure is provided...
